A. | HCHO |
B. | \[C{{H}_{3}}COC{{H}_{3}}\] |
C. | \[PhCOC{{H}_{3}}\] |
D. | \[PhCOPh\] |
A) \[A<B<C<D\]
B) \[D<B<C<A\]
C) \[D<C<B<A\]
D) \[C<D<B<A\]
Correct Answer: C
Solution :
Addition of HCN is nucleophilic addition. Greater the electron deficiency of carbonyl group higher the rate of reaction. Hence, the order is as \[Ph-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-Ph<Ph-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-C{{H}_{3}}<C{{H}_{3}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-C{{H}_{3}}<H-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-H\]You need to login to perform this action.
